To embed HTML templates in Go and render them dynamically, you need to follow these steps:
Create an HTML template file: Create an HTML file with your desired template structure. You can use Go's template syntax to add dynamic elements.
Import the html/template package: Import the html/template package to access the template and rendering functionality.
Embed the HTML template files: Use the go-bindata tool or go:embed directive (available in Go 1.16+) to embed the HTML template files into your Go executable. This step makes the templates available as file-like objects.
Using go-bindata:
go-bindata tool: Run go get -u github.com/go-bindata/go-bindata/... to install the go-bindata tool.go-bindata -pkg assets -o assets/assets.go templates/... to embed all HTML template files in the templates directory.Using go:embed directive (Go 1.16+):
//go:embed templates/* to the top of your Go file that will reference the templates. This directive tells the Go compiler to embed the templates directory.Parse the embedded template: Inside your Go code, parse the embedded template for rendering. If using go-bindata, the embedded template is accessible as a byte slice in the assets package.
tmplBytes, _ := assets.Asset("templates/mytemplate.html") // Replace with your actual template name
tmpl, err := template.New("mytemplate").Parse(string(tmplBytes))
if err != nil {
panic(err)
}
Define dynamic data: Prepare the data to be passed to the template when rendering. This can be accomplished using structs or maps.
data := struct {
Title string
Message string
}{
Title: "Welcome",
Message: "Hello, world!",
}
Render the template: Finally, render the template using the parsed template object and the dynamic data.
err = tmpl.Execute(w, data)
if err != nil {
panic(err)
}
This process allows you to embed HTML templates in your Go executable and render them dynamically by passing data to the templates.
